Because fundamentalist religion of all stripes has degradation of women at its core, and fundamentalist Christianity is no exception. Progressive Christians believe the Bible is a human document, a record of humanity’s multi-millennial struggle to understand what is good and what is God and how to live in moral community with each other. But fundamentalists believe the Bible is the literally perfect word of the Almighty, essentially dictated by God to the writers. To believe that the Bible is the literally perfect word of God is to believe that women are tainted seductresses who must be controlled by men.

Listen to early church father Tertullian: “You [woman] are the devil’s gateway: you are the unsealer of that (forbidden) tree: you are the first deserter of the divine law: you are she who persuaded him whom the devil was not valiant enough to attack. You destroyed so easily God’s image, man. On account of your desert—that is, death—even the Son of God had to die.”

Or take it from reformer John Calvin: “Woman is more guilty than man, because she was seduced by Satan, and so diverted her husband from obedience to God that she was an instrument of death leading to all perdition. It is necessary that woman recognize this, and that she learn to what she is subjected; and not only against her husband. This is reason enough why today she is placed below and that she bears within her ignominy and shame.”

Both Tertullian, a respected Catholic theologian, and Calvin, a leader of the Protestant Reformation, took their cues on this matter straight from the book of Genesis:

To the woman [God] said, I will make your pains in childbearing very severe; with painful labor you will give birth to children. Your desire will be for your husband, and he will rule over you. -Genesis 3:16

No matter how outrageous Santorum and Gingrich may seem to secularists and moderate people of faith, they are right on target for an intended audience of Bible believing fundamentalists. If you have any doubt, check out these 15 Bible passages.*

1. A wife is a man’s property: You shall not covet your neighbor’s house. You shall not covet your neighbor’s wife, or his male or female servant, his ox or donkey, or anything that belongs to your neighbor. Exodus 20:17

2. Daughters can be bought and sold: If a man sells his daughter as a servant, she is not to go free as male servants do. Exodus 21:7

3. A raped daughter can be sold to her rapist: If a man happens to meet a virgin who is not pledged to be married and rapes her and they are discovered, he shall pay her father fifty shekels of silver. He must marry the young woman, for he has violated her. He can never divorce her as long as he lives. Deuteronomy 22:28-29

4. Collecting wives and sex slaves is a sign of status: He [Solomon] had seven hundred wives of royal birth and three hundred concubines, and his wives led him astray. 1 Kings 11:3

5. Used brides deserve death: If, however the charge is true and no proof of the girl's virginity can be found, she shall be brought to the door of her father's house and there the men of her town shall stone her to death. Deuteronomy 22:20-21.

6. Women, but only virgins, are to be taken as spoils of war: Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man.Numbers 31:17-18

7. Menstruating women are spiritually unclean: When a woman has her regular flow of blood, the impurity of her monthly period will last seven days, and anyone who touches her will be unclean till evening. Anything she lies on during her period will be unclean, and anything she sits on will be unclean. Anyone who touches her bed will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening. Anyone who touches anything she sits on will be unclean; they must wash their clothes and bathe with water....

...The priest is to sacrifice one for a sin offering and the other for a burnt offering. In this way he will make atonement for her before the Lord for the uncleanness of her discharge. You must keep the Israelites separate from things that make them unclean, so they will not die in their uncleanness for defiling my dwelling place, which is among them. Leviticus 15: 19-31

8. A woman is twice as unclean after giving birth to a girl as to a boy: A woman who becomes pregnant and gives birth to a son will be ceremonially unclean for seven days, just as she is unclean during her monthly period. On the eighth day the boy is to be circumcised. Then the woman must wait thirty-three days to be purified from her bleeding. She must not touch anything sacred or go to the sanctuary until the days of her purification are over.

If she gives birth to a daughter, for two weeks the woman will be unclean, as during her period. Then she must wait sixty-six days to be purified from her bleeding.

When the days of her purification for a son or daughter are over, she is to bring to the priest at the entrance to the tent of meeting a year-old lamb for a burnt offering and a young pigeon or a dove for a sin offering. Leviticus 12: 1-8

9. A woman’s promise is binding only if her father or husband agrees: When a man makes a vow to the Lord or takes an oath to obligate himself by a pledge, he must not break his word but must do everything he said. When a young woman still living in her father’s household makes a vow to the Lord or obligates herself by a pledge and her father hears about her vow or pledge but says nothing to her, then all her vows and every pledge by which she obligated herself will stand.

But if her father forbids her when he hears about it, none of her vows or the pledges by which she obligated herself will stand; the Lord will release her because her father has forbidden her....

...A woman’s vow is meaningless unless approved by her husband or father. But if her husband nullifies them when he hears about them, then none of the vows or pledges that came from her lips will stand. Her husband has nullified them, and the Lord will release her. Her husband may confirm or nullify any vow she makes or any sworn pledge to deny herself. Numbers 30:1-16

10. Women should be seen and not heard: Women should remain silent in the churches. They are not allowed to speak, but must be in submission, as the law says. 1 Corinthians 14:34

11. Wives should submit to their husband’s instructions and desires: Wives, submit yourselves to your husbands, as is fitting in the Lord. Colossians 3:18

12. In case you missed that submission thing...:Wives, submit yourselves to your own husbands as you do to the Lord. For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior. Now as the church submits to Christ, so also wives should submit to their husbands in everything. Ephesians 5:22-24.

13. More submission – and childbearing as a form of atonement: A woman should learn in quietness and full submission. I do not permit a woman to teach or to assume authority over a man; she must be quiet. For Adam was formed first, then Eve. And Adam was not the one deceived; it was the woman who was deceived and became a sinner. But women will be saved through childbearing—if they continue in faith, love and holiness with propriety. 1 Timothy 2: 11-15

14. Women were created for men: For if a woman does not cover her head, she might as well have her hair cut off; but if it is a disgrace for a woman to have her hair cut off or her head shaved, then she should cover her head. A man ought not to cover his head, since he is the image and glory of God; but woman is the glory of man. For man did not come from woman, but woman from man; neither was man created for woman, but woman for man.1 Corinthians 11:2-10

15. Sleeping with women is dirty: No one could learn the song except the 144,000 who had been redeemed from the earth. These are those who did not defile themselves with women, for they remained virgins. They follow the Lamb wherever he goes. They were purchased from among mankind and offered as first-fruits to God and the Lamb. Revelation 14:3-4

This list is just a sampling of the Bible verses that either instruct or illustrate proper relationships between men and women. In context, they often are mixed among passages that teach proper relationships with children, slaves and foreigners. The Bible doesn’t forbid either contraception or abortion, but it is easy to see why Bible-believing fundamentalists might have negative feelings about both.

As futurist Sara Robinson has pointed out, traditional rules that govern male-female relationships are grounded more in property rights than civil rights. Men essentially have ownership of women, whose lives are scripted to serve an end—bearing offspring. It was very important to men that they know whose progeny they were raising, so sexual morality focused primarily on controlling women’s sex activity and maintaining their “purity” and value as assets. Traditional gender roles and rules evolved on the presumption that women don’t have control over their fertility. In other words, modern contraception radically changed a social compact that had existed for literally thousands of years.

Some people don’t welcome change. Since the beginnings of the 20th century, fundamentalist Christians have been engaged in what they see as spiritual warfare against secularists and modernist Christians. Both of their foes have embraced discoveries in fields as diverse as linguistics, archeology, psychology, biology and physics -- all of which call into question the heart of conservative religion and culture. Biblical scholars now challenge such “fundamentals” as a historical Adam, the Virgin Birth, the Resurrection and the special status that Abraham’s God gave to straight males.

Fundamentalists are fighting desperately to hang on to certainties and privileges they once saw as an Abrahamic birthright. If they can’t keep women in line, it’s all over. The future ends up in the hands of cultural creatives, scientists, artists, inquiring minds, and girls. It’s horrifying.
